Connectivity

The Cooler Master Tempest GZ2711 is equipped with two HDMI 2.1 and DisplayPort 1.4 video inputs, and a USB-C DP Alt Mode input. The latter supports 96 W Power Delivery, so that's the maximum amount of power it can deliver to a connected device, such as a laptop. The HDMI 2.1 inputs are limited to 24 Gbps instead of offering a full 48 Gbps bandwidth, so you'll be limited to a 144 Hz refresh rate when using HDMI.


Aside from the aforementioned USB-C port, the monitor also has a USB 3.2 Gen 1 Type-B upstream port and two USB 3.2 Gen 1 Type-A ports. Even though the product page makes no mention of an integrated KVM switch, the Tempest GZ2711 actually has one. What that means in practice is that the peripherals connected to two USB Type-A ports will automatically (and smoothly) switch between devices when you change video inputs. Thanks to that, you can control two devices with a single set of peripherals in a completely seamless way. This is a very useful feature, and one Cooler Master should definitely consider marketing.


Located between the USB Type-B and USB-C ports is a 3.5-millimeter audio output.

Power Consumption

The Cooler Master Tempest GZ2711 gets its power from a beefy external 240 W (24 V/10 A) power brick. I've used the Meross MSS315 Matter Smart Wi-Fi Plug and the accompanying mobile app to determine the monitor's power consumption at various brightness levels, as well as in Power Saving mode, which it enters as soon as the PC goes to sleep. My power consumption measurements are summed up in the chart below. They were made after resetting the monitor to factory defaults.



The measured power consumption of the Cooler Master Tempest GZ2711 is a complicated matter. Unlike most other OLED monitors, it doesn't offer a way to turn off the ABL (Auto Brightness Limiter) feature, so the brightness of the panel changes depending on the content currently being displayed – as does the power consumption. To keep things consistent between my other OLED monitor reviews, I measure the power consumption with the monitor showing the default Calman interface, which is mostly dark gray, and a 10% white pattern window.
